Steel is the correct answer because steel when on being applied heat will either change its state that too after hours because of its melting point being high or remain in that position only whereas wood turns into ashes...that is why we use metal utensils in the kitchen
An unbalanced force acting on an object results in the object's motion changing. The object may change its speed (speed up or slow down), or it may change its direction. Friction is a force that resists the motion or the tendency toward motion between two objects in contact with each other.

Answer:
<em>10500 J</em>
Explanation:
<em>Heat:</em> Heat is defined as a form of energy that brings about the sensation of warmth. The S.I unit of heat is Joules (J)
Q = cm(T₂-T₁)..................................... Equation 1
Where Q = quantity of heat, c = specific heat capacity of water, m = mass of water, T₂ = final temperature, T₁ = initial temperature.
<em>Given: m = 100 g = (100/1000) kg = 0.1 kg, T₁ = 25 °C, T₂ = 50 °C.</em>
<em>Constant: c = 4200 J/kg.°C</em>
<em>Substituting these values into equation 1</em>
<em>Q = 0.1×4200×(50-25)</em>
<em>Q = 420×25</em>
<em>Q = 10500 J</em>
<em>Thus the amount of heat needed to raise the temperature of 100 g of water from 25 °C to 50 °C = 10500 J</em>
